Do you have access to any of the isp pins (MOSI/MISO/CLK/RESET) are there any pins brought out to connectors ? If so you can wire the pins to a AVRISP, and connect to it through the avr studio, at least you may be able to read the fuses and lock pins, it is more than likely protected or updated through a bootloader interface. The code may even be encrypted (.enc) do you have source code to compile or are you trying to read it from the device and modify from there ?

I gave myself a quick lesson in ISP Programming. I now know that I know enough to get myself in trouble. I am looking for help and am willing to pay in order to avoid the inevitable pitfalls. any takers?
